The Prophet ﷺ said, "The Israelis used to be ruled and guided by prophets: Whenever a prophet died, another would take over his place. There will be no prophet after me, but there will be Caliphs who will increase in number." The people asked, "O Messenger of Allah ﷺ! What do you order us (to do)?" He said, "Obey the one who will be given the pledge of allegiance first. Fulfil their (i.e. the Caliphs) rights, for Allah will ask them about (any shortcoming) in ruling those Allah has put under their guardianship."  

قَاعَدْتُ أَبَا هُرَيْرَةَ خَمْسَ سِنِينَ فَسَمِعْتُهُ يُحَدِّثُ عَنِ النَّبِيِّ ﷺ قَالَ كَانَتْ بَنُو إِسْرَائِيلَ تَسُوسُهُمُ الأَنْبِيَاءُ كُلَّمَا هَلَكَ نَبِيٌّ خَلَفَهُ نَبِيٌّ وَإِنَّهُ لاَ نَبِيَّ بَعْدِي وَسَيَكُونُ خُلَفَاءُ فَيَكْثُرُونَ قَالُوا فَمَا تَأْمُرُنَا قَالَ فُوا بِبَيْعَةِ الأَوَّلِ فَالأَوَّلِ أَعْطُوهُمْ حَقَّهُمْ فَإِنَّ اللَّهَ سَائِلُهُمْ عَمَّا اسْتَرْعَاهُمْ  

Banu Isra'il were ruled over by the Prophets. When one Prophet died, another succeeded him; but after me there is no prophet and there will be caliphs and they will be quite large in number. His Companions said: What do you order us to do (in case we come to have more than one Caliph)? He said: The one to whom allegiance is sworn first has a supremacy over the others. Concede to them their due rights (i. e. obey them). God (Himself) will question them about the subjects whom He had entrusted to them. (Using translation from Muslim 1842a)   

قَاعَدْتُ أَبَا هُرَيْرَةَ خَمْسَ سِنِينَ فَسَمِعْتُهُ يُحَدِّثُ عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِنَّ بَنِي إِسْرَائِيلَ كَانَتْ تَسُوسُهُمُ الْأَنْبِيَاءُ كُلَّمَا هَلَكَ نَبِيٌّ خَلَفَ نَبِيٌّ وَإِنَّهُ لَا نَبِيَّ بَعْدِي إِنَّهُ سَيَكُونُ خُلَفَاءُ فَتَكْثُرُ قَالُوا فَمَا تَأْمُرُنَا؟ قَالَ فُوا بِبَيْعَةِ الْأَوَّلِ فَالْأَوَّلِ وَأَعْطُوهُمْ حَقَّهُمُ الَّذِي جَعَلَ اللهُ لَهُمْ فَإِنَّ اللهَ سَائِلُهُمْ عَمَّا اسْتَرْعَاهُمْ  

[Machine] Narrated by the Prophet ﷺ : The children of Israel were ruled by their prophets. Whenever a prophet passed away, another prophet would succeed him. But there will be no prophet after me, and there will be many successors. They asked, "What do you command us to do?" He said, "Give them the bay'ah (pledge of allegiance) one after another, and fulfill their rights. Verily, Allah will question them about how they looked after their subjects."  

عَنِ النَّبِيِّ ﷺ قَالَ كَانَتْ بَنُو إِسْرَائِيلَ تَسُوسُهُمُ الْأَنْبِيَاءُ كُلَّمَا هَلَكَ نَبِيٌّ خَلَفَهُ نَبِيٌّ وَإِنَّهُ لَا نَبِيَّ بَعْدِي وَسَتَكُونُ خُلَفَاءُ يَكْثُرُونَ قَالُوا فَمَا تَأْمُرُنَا؟ قَالَ فُوا بَيْعَةَ الْأَوَّلِ فَالْأَوَّلِ وَأَعْطُوهُمْ حَقَّهُمْ فَإِنَّ اللهَ سَائِلُهُمْ عَمَّنِ اسْتَرْعَاهُمْ  

"كَانَتْ بَنُو إِسَرائِيل تَسُوسُهم الأنْبِيَاءُ - كُلَّمَا هَلَكَ نَبيٌّ خَلَفَهُ نَبيٌّ، وإِنَّهُ لَا نَبِيَّ بَعْدِى - وَسَتَكُونُ خُلَفَاءُ فَيَكْثُرون - قالوا: فَمَا تأمُرنَا؟ ، قَال: بَبَيعَةِ الأوَّلِ فالأوَّلِ، وأَعْطُوهُمْ حَقَّهمُ الَّذِي جَعَلَ الله لَهُمْ، فإِنَّ اللهَ سَائِلَهُمُ عَمَّا اسْترعَاهُم".  

"عَنْ أَبِي هُرَيْرَةَ قال: قَالَ رسُولُ اللهِ ﷺ : إِنَّ بَني إِسْرَائيلَ كَانَتْ تَسُوسُهُمُ الأَنْبِيَاءُ، كُلَّمَا هلَكَ نِبَيٌّ قَامَ نَبِيٌّ، وإِنَّهُ لا نبيَّ بَعْدِي، قَالُوا: يَا نَبِيَّ الله فَمَا يكُون بَعْدَكَ؟ قَالَ: يَكُونُ خَلَفًا وتكْثُر، قَالوا: فَمَا تأمُرنَا؟ قَالَ: وَفُّوا بَيْعَةَ الأَوَّلِ، وَأَدُّوا إِلَيْهِم مَا عليكمْ فَإِنَّ الله - تَعَالَى- سَائِلُهُمْ عن الَّذِي بِكُمْ، وَفِي لَفْظٍ سَائِلهم عَمَّا اسْتَرْعَاهُمْ".
